Research and Discussion on the Application of Logging Technology in Geological Exploration Engineering

Abstract

In this paper, the development history of geophysical logging technology was reviewed, the application status of logging technology in the geological exploration of hydrology, marine oil and gas, and marine natural gas hydrate was introduced, logging response characteristics and identification methods in various geological exploration projects were summarized, and the current situation and development trend of new logging technology was discussed. With the gradual deepening of complex and unconventional oilgas exploration and development, there are an increasing number of highly deviated wells, horizontal wells, and vertical wells with complex well conditions, promoting the development of unconventional reservoir logging technology as the main logging technology at present. It is urgent to deeply explore basic logging theories, formation testing, downhole fluid analysis, petrophysical analysis and logging response experiments, accelerate the research and development of new logging technologies and equipment, improve the ability and level of logging evaluation for complex reservoirs, and effectively promote the quality and efficiency improvement of unconventional oil-gas exploration.
